A decent drill makes a difference, but the operator makes the biggest differece...
When drilling metal i find ( even with hss) slow speeds and plenty of pressure is the key, second you go to fast, smoke flys, tip melts and bits wrecked..
Slow and steady and the drill bits will last years, or months if you use them alot like I do! Drill press / pillar drill also everytime where its possible, will safe bits this way also!
Also worth noting, ive never had proper "cutting fluid" in my life until a few months ago when i aqquired a bottle for free...wow..never look back, well worth having, magic stuff!
